AgWeatherNet Weekly Weather Outlook for June 9 to June 15, 2018

Cooler and Unsettled This Weekend; Becoming Warmer and Drier Early Next Week

Nic Loyd, Meteorologist, 509-786-9357

An incoming low pressure trough will lead to a cooler and unsettled weekend, with clouds, showers, and gusty breezes. Although there are likely to be lingering showers into Saturday morning in central Washington, a transition from southerly to westerly downslope flow should quickly shift the main threat of rain to western and far eastern Washington by mid day Saturday. However, even after the initial front has departed the region, the cool air aloft and instability could mean isolated showers just about anywhere or anytime, and especially during the afternoons.

Overall, this weekend does not look to be ideal for heat and sun loving hikers considering a trip to the mountains. Instead, alpine recreationalists can expect a chilly rain or higher elevation snow. In fact, Pullman may only reach the upper 50s tomorrow due to cool air and showers.

Monday is set to be the transition day, as the pattern shifts toward a somewhat benign regime by Tuesday. Following a cool Monday morning during which chilly spots could dip below 40 degrees, warmer temperatures are predicted for Tuesday and Wednesday, along with rather dry conditions. However, another weaker system is poised to transit the region later next week. As a result, slight cooling is anticipated to occur, along with a modest increase in wind speeds and even possible showers in the west.

A special note to cherry growers: Scattered to widespread showers are expected later today (Friday) and into Saturday morning across normally arid central Washington. Although amounts should not generally be heavy, many areas will receive at least light rainfall. From a potential cracking perspective, the good news is that temperatures will not warm up rapidly on Saturday. Also, breezes are possible at times, although whether there will be any help from increased winds during or just after any rainfall is not certain, and will vary by specific location. In any event, the situation should be monitored, and now may be an appropriate time to set rain threshold alerts for your key AWN sites.
